Abstract

The instrument measures eye movement, having a light source emitting a measuring ray at the front part of the eye. This is reflected through a projection lens onto a photo-receiver, which emits signals dependent on the position of the picture projected onto it. The reflected optical axis (6) of the projection lens (3) is coaxial with that (6) of the eye (1), and a mirror (8) is interposed between the eye and the lens, reflecting the measuring ray (10).
